CIRCLE is an annual gathering for people shaping the built environment – owners, investors, designers, engineers, consultants, and innovators.
An energetic mix of familiar faces, new collaborators, and the ideas that matter next, CIRCLE is rooted in LEED, but not limited to it.
Part retreat, part conference, CIRCLE is a high-trust space to connect, learn, and find inspiration.
At Circle 2026, we’ll be exploring the theme of Forging Resilience. In a time defined by rapid transformation, resilience has become essential for businesses, cities, investors, and the built environment.
